The next Transatlantic Tandem Talk (TTT) by the University of Cologne New York Office and partners will feature an expert discussion with Dr. Jannik Martens, Columbia University and Prof. Dr. Janet Rethemeyer, University of Cologne on the global impact of climate change in the Arctic.
The Arctic is warming three times faster than the rest of our planet. The melting of ice sheets and glaciers raises concerns about global sea-level rise, while the thawing and degradation of Arctic permafrost soils may release large amounts of greenhouse gases, causing additional warming. Although Arctic change will likely impact the global climate system and society, our understanding of future developments in this environment remains limited.
To comprehend current and future changes in the Arctic region, scientists study climate archives such as ocean and lake sediments and permafrost to find clues about how past changes in Arctic climate affected the environment.
This TTT will illustrate the current research frontiers and open research questions in Arctic research, seeking to illuminate past climate changes and how permafrost may impact the climate system. The discussion will provide insight into recent Arctic expeditions and showcase international collaborations between the University of Cologne and leading US-based institutions. Following the TTT, there will be a virtual tour through the core repository of the Lamont-Doherty Earth Observatory of Columbia University in NYC, which houses over 20,000 sediment cores from across the globe.
